ATTORNEYS LASTING, DEVICE FOR SHOES The present invention relates to alasting device for the lasting of the toe or heel part of a shoe, andmore particularly to a lasting device whereby the lasting operation onthe toe or heel part of a shoe can be performed simultaneously with thelasting operation on the shank of the shoe.

In the case of lasting a shoe upper in conformity with a wood last, theshoe upper is lasted by means of a shoe upper lasting device called thewiper under a tightly pulled condition along the wood last so as not toproduce wrinkle. At the same time, said lasted upper piece is stuck byan adhesive on to the insole attached temporarily to the bottom of thewood last. It is however impossible to perform such lasting operationsimultaneously due to the shape of shoes. Hence, it is a normal practiceto divide it into the toe, heel and shank parts thereby lasting eachpart by means of a respective specialized wiper.

The present inventor proposed previously a lasting device for shoes perUS. Pat. No. 3,435,473. With this lasting device, however, the shankpart of a shoe is lasted at first, and then the entire shoe is lastedusing another lasting device for the toe and heel parts.

The present inventor has made an improvement on the above-mentionedlasting device for shoes so as to enable the simultaneous lastingoperation on the shank and toe parts or on the shank and heel partsthereby to shorten the time required for lasting operation, in additionto making it possible to perform lasting operation by means of a singlelasting device regardless of the size and shapes of the shoes to belasted.

Numeral 40 denotes a cover plate adapted to cover the upper surface ofsaid wiper plate and moreover, to hold pinion gears in a freelyrotatable manner.

The operation of the present invention, having the aforementionedconstruction, will now be illustrated hereinafter.

To begin with, the upper of the shoe 5 is fitted over the wood last 6and the insole of the shoe is fixed and applied by a powerful adhesiveto the lasting leather at the toe and shank parts of the shoe.

In this condition, the wood last 6 is fitted on the fitting stand 8 andthen the control circuit (not shown) of each oil pressure mechanism isactuated by pushing switches (not shown) by hands or foot whereby ahydraulic fluid is fed into the oil pressure mechanism 4 at first andthe piston rod 4' starts to come down simultaneously bringing theholding means 7 downwardly until its end comes to a points where saidend of holding means 7 is protruded downwardly about a distance equal tothe thickness of a sheet of a shoe upper material beneath said wiper asits stops.

When the operation of said oil pressure mechanism 4 is stopped and ahydraulic liquid is fed into the oil pressure mechanism 9 the wood lastbeing attached to the piston rod 10 is raised as said rod 10 goes upuntil it reaches the lower end of said holding means 7 where it causesthe oil pressure mechanism 9 to be stopped and thereby simultaneouslystrongly holding the wood last 6 both from above and below the last.

As the wood last 6 is held firmly as above mentioned, the oil pressuremechanism connected to the operating levers 17, 17 is actuated so as tocause the upper ends of said operating levers 17, 17 to be rotated inthe direction of arrow, simultaneously sliding levers 15, towardopposite sides of the wood last and thereby each of pincers 16, 16 ispressed against the leather A of the shank part of the shoe beingraised. As the pincers move forward, the shank leather A is pushed downover the insole plate of the shoe, said leather firmly attached to theinsole part by a strong downward pressure exerted by the furtheradvancement of said pincers l6, l6.

Concurrently with the lasting action of said lasting mechanism 13, 13for lasting the shank part leather, a hydrau lic liquid is also fed tothe oil pressure mechanism 39 thereby to cause a base plate 20 connectedto its piston rod 39' to be moved forward to the direction of the woodlast 6. Consequently, driving pinion gears 37, 37 engaged with rackmembers 38, 38 are caused to be rotated, and furthermore, pinion gears36, 36 unitarily formed with said gears 37, 37 are also rotated with aresult that plate plungers 23, 23 engaged with said gears are rotatedtogether with their wipers in the direction of arrow, respectively.Accordingly, the open end of the U-shaped notch formed collectively bywiper plates 26, 26 and 28, 28 is gradually narrowed centered around theoverlapped pivot portions 27, 27. The above-mentioned narrowing speed isset to be less than the forward feeding speed of the base plate 20. Asthe base plate is advanced and movable wipers 28, 28 approach slightlyto the toe part of the shoe, the oil channel of the oil pressuremechanism 4 is switched over to cause its piston rod 4' to be raised.(This action is to be performed simultaneously with the lasting of theshank part.) As the pressure applied over the wood last 6 by the oilpressure mechanism 4 has been released, the entire body of the wood last6 is slightly raised by a pushing force applied by the oil pressuremechanism 9 thereby to press the toe part (same as the shank part) ofthe shoe being set to the wood last against the lower surface of thewiper plate. Each of said wiper plate, therefore, is subjected to apressure from below as it moves forward with its size becoming narrowerwhereby the protruding leather B at the toe part is lasted in asqueezing manner, so that said lasting part is securely attached to theinsole part of the shoe.

When the control circuit is opened, each oil pressure mechanism isreturned to its original position to be kept in the next lasting state.

In instances of lasting said shank part and toe part, if the end portionof movable wiper plate 28, 28 come in contact with the lasting pincers16, 16 of the shank part, the movable wiper plates 28, 28 will recedeinto recessed portion 25', 25', as the base plate 20 moves forward, inopposition to the forces of coil springs 33, 33 so that the lastingoperations on the toe part of the shoe will not be hampered, andfurthermore, the toe part and the shank part of the shoe can be lastedsimultaneously regardless of the size of the shoe.

In the above explanation, the process for lasting the shank and toeparts of shoes has been described, but the invention is not limited tothe above so that the process can be also carried out for lasting theshank and heel parts in the same manner, with identical devices as shownin FIG. 6.

From the foregoing description, it will be understood that the device ofthis invention carries out the lasting of the shank and toe portions, orthe heel portion by a single device simultaneously. Therefore, thelasting operations on a shoe have been expedited with a drastic increasein its work efficiency together with a substantial profit in terms ofthe shoe cost. Furthermore, since the straight line sections, other thanthe circular portions opposite to the toe and heel parts of shoes, of

the wiper plate for lasting the toe and heel portions are made freelyflexible or movable, it has become possible to perform lastingoperations on any size of shoe. Moreover, the force that pushes the woodlast upwardly from below is applied to the lower surface of the wiperthrough elimination of a force pushing the wood last downwardly fromabove, which enables the lasting operation to be performed with thelasting leather at the toe, shank or heel portion being completely andsnugly fitted over the last under the tightly pulled condition inwardly.It will be understood that the device of the present invention hasexcellent features as mentioned above.
